build failed: unexpected EOF reading a line

build failed: unexpected EOF reading a line

Hi all,

I'm having issues using guix build. I'm suspecting some misconfiguration on
my end.

Since there are some stuff missing in guix that I use (i3blocks for
example) I thought I could try and create package definitions from them. I
haven't got my GuixSD working yet so I'm using guix running on Arch Linux.

I thought that it might be something wrong with my recipe I was writing. So
I tested to build the GNU Hello package from the manual (Defining Packages
<https://www.gnu.org/software/guix/manual/html_node/Defining-Packages.html#Defining-Packages>).
I copied it into a file called gnu/packages/hello.scm
After that I ran "guix build -L$(pwd) hello".
But I'm getting these errors:

> guix: offload: command not found
> Try `guix --help' for more information.
> guix build: error: build failed: unexpected EOF reading a line
>

Not sure why it complains about missing offload command. I haven't setup it
up but when running "guix offload test" it prints out:

> guix offload: testing 0 build machines defined in
> '/etc/guix/machines.scm'...
>

But that's not what's blocking my, instead it's the EOF error.
My first thought was that I must have missed a newline after the
(define-public hello ...). Turns out that wasn't the case. Any idea what I
have missed? I'm still a complete noob when it comes to guile so I'm not
sure how to debug/trace the error.

I've attached the hello.scm

Thanks.

How did you set up guix-daemon?

Behind the scenes, guix-daemon invokes the internal ‘guix offload’
command.  That command requires Guile-SSH¹.  In your case, it looks like
Guile-SSH was found at configure-time when building Guix, but is now
missing at run time, hence this “offload: command not found” error.

Could you make sure the GUILE_LOAD_PATH environment variable seen by
guix-daemon points to Guile-SSH?

HTH,
Ludo’.

Awesome.

Perhaps you should report the issue in AUR so that they can add these
lines to the .service file by default.

Thanks for your feedback,

Wrote a comment about it on the AUR. See if it gets added.

Anyway thanks again for your help.
